Guillermo Klein moved from his native Argentina to Boston in 1990 to study at Berklee College of Music.

In 1993 he moved to New York where he formed an inventive 17-piece big band. The band played Sunday nights at the underground club Smalls throughout 1995.

Several years later, a newer, larger club called the Jazz Standard gave the Guillermo Klein Big Band a regular Monday night gig for several months. Klein also performed and recorded with a ten-piece ensemble called los Guachos, which featured the likes of Bill McHenry, Chris Cheek, Ben Monder, and others.

The band's debut on Candid Records was never released, but Sunnyside picked up Los Guachos Vol. 2 for release in 1999.

Unfortunately for the New York jazz scene, Klein moved back to Argentina in September of 2000

On May 10th, Sunnyside Records will release Una Nave, the new album the brilliant and enigmatic Guillermo Klein. Best known for his work with his large ensemble, Los Guachos, Guillermo returned to Argentina,the country of his birth to record this latest offering.

If you have never heard his music before or even if you have, we STONGLY encourage you listen to sound clips in our store. Trust us on this one. Words fail to describe his music.

Below is Ben Ratiff's May 9th review of Guillermo Klein's album, "Una Nave." The album is available for purchase on May 10th. You can purchase the CD or download in our online store.

THE NEW YORK TIMES - May 9th
Ben Ratliff

"The composer, pianist and bandleader Guillermo Klein lived in New York from 1993 to 2000 before moving to Argentina, where he's from, and Barcelona, where he currently lives. But he was a source of inspiration, and he is still talked about. His jazz, if you want to call it that, is built from the ground up, starting with ideas about instrumentation, then rhythm, then harmony, then gesture. In one of his large ensemble sets, there could be brass choirs, Cuban rhythm, fugue-like passages, talking, whistling, mechanical repetitions over a groove, and bits of aerated rock.

Many of the better young jazz improvisers in New York gravitated toward him, but then he was gone. Some of his recent work has just trickled out in the past month: on a live album, "Guillermo Klein y Los Guachos Live in Barcelona" from Fresh Sound, and also on "Una Nave," recorded for Sunnyside in 2002 in Buenos Aires, with Argentine musicians.

Perhaps because he undercuts his own keyboard playing, often restricting himself to chorded vamps, Mr. Klein functions as a true composer, rather than a stirrer of the pot within certain fixed jazz idioms. (Sometimes he can remind you of Hermeto Pascoal and Milton Nascimento, other examples of uncontainable thinkers.)

The voice is part of his concept, and though he has no jazz-singing voice - it's more like a whispered growl - he uses it on several tracks here, including the beautiful "Nave," which often breaks up its lyric into a single word per measure; "Piernas," an aching, slow-moving song with brilliant harmony; and "Luci," a short and deceptively simple voice-and-piano piece. Elsewhere, "Venga" is all-out, static-harmony ensemble playing that keeps slamming down in the tonic chord. "Luminarias" and "Niza" are based on tango and milonga forms, and "La Ultima" uses the band's two trumpeters, Juan Cruz de Urquiza and Richard Nant, to trade off tiny melody shards over varying meters. It's an excellent record, and not like much else out there."

The New York Time article on Guillermo Klein who debuts at the Village Vanguard on June 132006-06-03

WHEN Guillermo Klein brings his band to the Village Vanguard for a week of shows starting June 13, it will be the return of a beloved musician who never got the chance to use the momentum he was building on New York's jazz scene in the late 1990's. Instead he slipped away to Argentina and then to Spain. In New York we usually don't draw the short straw like this. We have heard dispatches from Mr. Klein — three fascinating records — but have had to live with the fact that his evolution was taking place somewhere else.

Guillermo Klein's Los Guachos, 11 musicians, are making unnameable
music at the Village Vanguard this week, rich and sticky in rhythm and
harmony. It doesn't have much to do with current trends in the rest of
jazz, but only jazz musicians could be making it. It is not the only way or
the true way; it is just one excellent, original way. Ben Ratliff, The New York TimesJune 2006 read the full article

Guillermo Klein has built some fascinating bridges between jazz, pop,
classical music and the chacareras and tangos of his native Argentina.
His best music also carries smart harmonic ideas and surprising bolts
of lyricism, but virtually all of it deals purposefully with the subject of
groove. Nate Chinen, The New York Times-February 2007read the full article

The Vanguard has invited him back for two weeks this year. Though the music sounds even stronger, Mr. Klein is still holding it together without a lot of self-serving flash. He deserves credit for this, especially because he has a specific sound.

WHEN Guillermo Klein brings his band to the Village Vanguard for a week of shows starting June 13, it will be the return of a beloved musician...His music resembled nothing else, especially as it moved toward grooves and away from the harmonic exercises he had learned in music school. It was jazz, of a kind, but it included brass choirs, counterpoint, drones, Argentine and Cuban rhythms and a lot of singing.Ben Ratliff, The New York Times - June 2007read the full article

"I'm not a jazz composer", states Guillermo Klein, pianist and leader of the 11-piece ensemble Los Guachos. "The term 'jazz composition' is vague, but it's ofter used to explain instrumental songs with solos, which is cool with me."David Adler, JazzTimes - August 2008read the full article
